Stone glacier belt question

[click9]

Question for the experts here and I guess I'm too impatient to wait to call Stone glacier in the morning. Will a Krux evo belt work with the Xcurve frame? I only ask because the evo belt looks a little different than the newer krux/xcurve belt in the photos I see. The evo frame was delivered today with a large belt (which I know I need that size now) and have an xcurve frame coming with a medium belt. Hoping I can just switch the belts to compare the two, then sell the setup I'm not gonna keep. Thanks in advance.
